Our latest research explores the potential of fully-passive static electromagnetic surfaces, also known as smart skins, for boosting network coverage and connectivity! Here's the key takeaway: These surfaces offer a cost-effective and simpler alternative to reconfigurable intelligent surfaces (RIS) - without the need for complex channel estimation. But, a critical question remains: what's the optimal angle for pre-configuring these static surfaces? Our paper tackles this challenge! We propose a design method that optimizes average spectral efficiency and coverage probability for vehicle-to-vehicle (V2V) communication, leveraging statistical knowledge of signal angles. This versatile approach can be applied to various scenarios beyond V2V. The outcome? By strategically designing smart skins, we can significantly enhance network connectivity, paving the way for a more robust and reliable wireless future! Interested in learning more? Check out our full paper! This work is a result of a great collaborative effort with Silvia Mura, Dario Tagliaferri, Marouan Mizmizi, and Umberto Spagnolini. Many thanks to my co-authors for their invaluable contributions! #6G #reconfigurableintelligentsurfaces #metasurfaces #coverage #spectral_efficiency #smartskins #electromagneticskins

Our transparent antenna design has been featured as a hot topic paper in the field of antennas and propagation (WHAP: What’s Hot in Antennas and Propagation) by IEEE Transactions on Antennas and Propagation. Paper Title: A Transparent Antenna Using Metal Mesh for UWB MIMO Applications Paper Link: https://lnkd.in/d_GBSn45 Video Link: https://lnkd.in/dM4Tjq9Z This project utilizes metal mesh as the antenna's main body, achieving high transparency, efficiency, ultra-wideband capabilities, MIMO support, and low coupling. It effectively addresses the shortcomings of traditional transparent antennas, such as costliness and inefficiency, by employing cheap materials. Our project offers a solution for balancing indoor, compact spaces with large-scale antenna arrays, driving innovation and applications in 6G indoor communication antenna technology. This accomplishment has garnered the attention of numerous scholars in the field. Author: Dr. Yao Yu, Associate Professor Yu Shao, Professor Jiliang Zhang, and Professor Jie Zhang. Funding support: European Union projects H2020-MSCA-IF-GATE (843133) and H2020-MSCA-IF-AceLSAA (752644). Abstract: This article presents a transparent ultrawideband (UWB) multiple-input–multiple-output (MIMO) antenna based on a wired metal mesh (MM) structure. Transparent antennas (TAs) can be integrated into various building materials with little visual impact to facilitate flexible massive indoor wireless device deployment. The proposed antenna achieves 77% transparency by hollowing out both metal and substrates into a mesh shape, while maintaining more than 83% radiation efficiency. The MIMO antenna consists of four elements, each being a coplanar waveguide (CPW)-fed UWB monopole and adjacent elements being placed orthogonally to produce dual polarization. The operating band of the MIMO antenna spans over 3.2–11.2 GHz. A parasitic decoupling structure aligned with the mesh grid is designed to enhance the isolation between MIMO elements without degrading the transparency. Within the entire operating band, the isolation between any two elements is more than 20 dB. The peak gain varies from 3.3 to 7.2 dBi within the bandwidth. The envelope correlation coefficient (ECC) is less than 0.004. The channel capacity and time domain response are analyzed. The antenna can be easily fabricated by conventional printed circuit board (PCB) and laser cutting techniques at a low cost.

#LT3042IDD#TRPBF The LT®3042 is a high performance low dropout linear regulator featuring LTC’s ultralow noise and ultrahigh PSRR architecture for powering noise sensitive RF applications. Designed as a precision current reference followed by a high performance voltage buffer, the LT3042 can be easily paralleled to further reduce noise, increase output current and spread heat on the PCB. The device supplies 200mA at a typical 350mV dropout voltage. Operating quiescent current is nominally 2mA and drops to <<1μA in shutdown. The LT3042’s wide output voltage range (0V to 15V) while maintaining unity- gain operation provides virtually constant output noise, PSRR, bandwidth and load regulation, independent of the programmed output voltage. Additionally, the regulator features programmable current limit, fast start-up capa- bility and programmable power good to indicate output voltage regulation. The LT3042 is stable with a minimum 4.7μF ceramic output capacitor. Built-in protection includes reverse bat- tery protection, reverse current protection, internal current limit with foldback and thermal limit with hysteresis. The LT3042 is available in thermally enhanced 10-Lead MSOP and 3mm × 3mm DFN packages.

#FTTH_Design In the design of Fiber-to-the-Home (FTTH) projects, how do you choose the type of splitter, and what is the difference between the two types? The choice between FBT (Fused Biconical Taper) splitters and PLC (Planar Lightwave Circuit) splitters in AirPON (Airborne Passive Optical Network) technology depends on several factors: 1. FBT Splitters: - Advantages: FBT splitters are cost-effective and simple to manufacture. They are suitable for various optical splitting applications, including AirPON. - *Operation:* FBT splitters use a fused fiber technology to divide or combine optical signals. They are available in different split ratios. - Considerations : FBT splitters may have a larger physical size and may not be as scalable for very high port counts. They are often used in applications where space and cost are critical factors. 2. PLC Splitters: - Advantages: PLC splitters are compact, offer high port count options, and provide better scalability. They are suitable for applications where precise splitting ratios and a high degree of reliability are required. - Operation: PLC splitters use a planar lightwave circuit, typically constructed on a silica substrate, to split optical signals. They are available in various configurations and can achieve more precise splitting ratios than FBT splitters. - Considerations: PLC splitters may be more expensive than FBT splitters, but they offer advantages in terms of size, scalability, and performance. the choice between FBT and PLC splitters will depend on factors such as budget constraints, space availability, scalability requirements, and the specific needs of the optical network. If precise splitting ratios, compact size, and scalability are crucial, PLC splitters might be preferred. However, if cost-effectiveness is a primary consideration and space is less constrained, FBT splitters may be a suitable choice. #FTTH #FTTx #PON

Every now and then, being a control freak is necessary. Particularly, when running IV semiconductor characterization. Many devices, like Zener diodes, are notoriously temperamental, exhibiting different behaviors depending on the current flow and voltage. The Rohde & Schwarz #NGU400, features a four-quadrant architecture, meaning it can supply both positive and negative voltages or currents, acting as a source or sink in both polarities to give you ultimate control.

[𝐀𝐧𝐭𝐞𝐧𝐧𝐚] The antenna is a very important component of communication systems. By definition, an antenna is a device used to transform an RF signal, travelling on a conductor, into an electromagnetic wave in free space (transmit mode), and to transform an RF electromagnetic wave into an electrical signal (receive mode). The choice of antenna is very important for a transmitting - receiving communication system. The antenna must be able to radiate or receive efficiently so the power supplied is not wasted. lets start with 𝐈𝐧𝐯𝐞𝐫𝐭𝐞𝐝-𝐅 𝐀𝐧𝐭𝐞𝐧𝐧𝐚 (𝐈𝐅𝐀): An inverted-F antenna is a type of antenna used in wireless communication, mainly at UHF and microwave frequencies. It consists of a monopole antenna running parallel to a ground plane and grounded at one end. The antenna is fed from an intermediate point a distance from the grounded end. The design has two advantages over a simple monopole: the antenna is shorter and more compact, allowing it to be contained within the case of the mobile device, and it can be impedance matched to the feed circuit by the designer, allowing it to radiate power efficiently, without the need for extraneous matching components. IFA is a better antenna compared to MIFA for radiation. Given space availability IFA antenna is a better antenna than a MIFA antenna. It has better efficiency. However, it requires more area compared to MIFA. The IFA is recommended for applications in which one of the antenna dimensions is constrained, such as in a heart rate monitor. FIGURE (𝐈𝐅𝐀) : DO NOT PLACE ANY COPPER ON THE BOTTOM SIDE OF THE PCB IN THE WHITE AREA.
